Function of the operator controls of the power supply modules 

FMR momentary-
contact pushbut-
ton

For acknowledging and resetting a fault indicator after correcting the
fault

Standby switch

Switches the output voltages (5 VDC/24 VDC) to 0 V by intervening in
the control loop (no mains disconnection).

•

  I

  : Output voltages at rated value

•

     : Output voltages 0 V

 

BATT INDIC
switch

Used for setting LEDs and battery monitoring

Where one battery can be used (PS 407 4A, PS 405 4A):

•

OFF: LEDs and monitor signals inactive

•

BATT: BAF/BATTF LEDs and monitor signals active

Where two batteries can be used (PS 407 10A, PS 407 20A, PS
405 10A, PS  405 20A):

•

OFF: LEDs and monitor signals inactive

•

1 BATT: Only BAF/BATT1F LEDs (for battery 1) active.

•

2 BATT: BAF/BATT1F/BATT2F LEDs (for batteries 1 and 2) active.

Voltage selector 
(if present)

For setting the primary voltage (120 VAC or 230 VAC), protected by its
own cover.
(Please note the following information)

Battery compart-
ment

For backup battery (batteries)

Power connec-
tion

3-pin connector for line voltage connection (do not plug in or remove
when power is on).

One of the following power supply modules could be damaged:

Power supply module PS 407 4A

(6ES7407-0DA00-0AA0)

Power supply module PS 407 20A

(6ES7407-0RA00-0AA0)

If you set the voltage selector to 120 V on these AC power supply modules and
connect the power supply modules to a 230 V power system, it might damage the
power supply modules. Warranty is excluded in such a case.

Set the voltage selector on these AC power supply modules to the line voltage.
